Can a US citizen just move to the Virgin Islands?

Yes. The US Virgin Islands (St Croix, St Thomas, St John) are a US territory, so any US citizen can move there with no visa, no residence permit, and no immigration paperwork. A US passport, driver’s licence, or birth certificate is all the ID needed to fly in and rent or buy from day one. Practical complications begin after landing: the USVI has its own tax system (the “mirror code”), residency rules that affect federal vs territorial filing, separate Bar admission for legal professionals, and territory-specific licensing for medicine and some trades. Cars usually ship from the mainland (roughly $1,200 to $1,800 plus taxes and fees), household goods follow on the same carriers. St Croix’s moderate cost of living at $3,600 per person per month is the operational hurdle for most movers rather than legal entry. For the full cost picture, see our St Croix cost of living page.
